The Milwaukee Bucks never came close to solving Steve Nash and the Phoenix Suns on Sunday at US Airways Center, falling, 109-93, to go winless on their five-game western road swing.

And the Bucks extended their losing streak in Phoenix to a mind-boggling 24 games, a place they haven't won since 1987, when Terry Cummings, Paul Pressey and Sidney Moncrief were on the roster.

Nash had eight assists on the Suns' first eight baskets and 10 assists in the first quarter alone, and he finished with 17 assists while playing just three quarters.

The 37-year-old point guard and the rest of the Suns starters weren't required in the final quarter with the Suns building a 91-66 lead after three periods. Phoenix's biggest lead was 28 points early in the fourth quarter.

"We were just really soft on him," Bucks coach Scott Skiles said of Nash. "You let Steve dribble around like that, and he's got such great vision.

"Then when we did kind of bottle him up a little bit, we were just so slow to recover back to the shooters. Obviously, it's the worst defense we've played so far this year, and it hurt us."

Milwaukee (2-6) remained winless in six road games and was not competitive one night after testing the Los Angeles Clippers in a 92-86 loss at the Staples Center.

Bucks point guard Brandon Jennings admitted he was tired after playing for the fifth time in seven days.

"It's very disappointing to go 0-5 on the West Coast trip," Jennings said. "But the good thing about it is we have a chance to go home and try to get our record back up and make some noise.

"We've just got to come together as a team. Me playing a lot of minutes, it can really get to you."

Center Andrew Bogut was missing for the final four games of the road trip after heading back to Australia on an excused absence due to a family issue.

His agent, David Bauman, and Skiles confirmed Sunday that Bogut was on his way back to the United States and would be available to play Tuesday when the Bucks meet the San Antonio Spurs at the Bradley Center.

"We're going through a lot right now with guys being hurt," Bucks guard Stephen Jackson said. "We've just got to figure it out. We're going to get through this, though."

The Bucks also were missing Luc Richard Mbah a Moute, Beno Udrih and Mike Dunleavy Jr. due to injuries.

Milwaukee squandered a 21-point halftime lead in Sacramento on Thursday and also led most of the game in Denver, on the first game of the trip.

"Yes we can (bounce back)," said Bucks veteran Drew Gooden, who started at center during the last four games of the trip. "It's just everybody digging deep and trying to fight."

Suns center Marcin Gortat had plenty of room to shoot and made 9 of 10 field-goal attempts while scoring a game-high 18 points.

Channing Frye went 6 of 7 from the field and sank all 4 three-pointers he attempted to finish with 16 points.

Rookie forward Markieff Morris was impressive with 13 points and 10 rebounds as Phoenix (4-4) won for the third time in its last four games.

Seven Suns players scored in double figures as Phoenix shot 56% from the field (43 of 77) and was 10 of 22 from beyond the arc.

"Our starters vs. their starters, we could never get any traction," Skiles said.

One bright spot for the Bucks was the play of rookie forward Tobias Harris, who had his playing-time restriction lifted and scored a team-high 15 points in 23 minutes.

He was on a 10-minute limit in his return against the Clippers after battling dehydration and muscle soreness.

"It felt good just to be out there not on a limit and know I could gradually get my rhythm in the game," Harris said. "I just tried to be aggressive.

"That's a huge thing for me, getting in the shape I was in before. It will come with some practices and workouts. Now that I'm officially cleared, I'm not just sitting and watching and doing nothing at all."

Fellow rookie Jon Leuer had 11 points and six rebounds, and Ersan Ilyasova was the only starter in double figures with 11 points and eight rebounds.

"You can see he (Harris) is aggressive, and he brings an element we don't have, from a size and athleticism standpoint," Skiles said. "He and Jon Leuer both, they believe in themselves.

"They play with confidence, and it's one of the reasons they're both going to continue to get time.

"You just caught a glimpse of what Tobias can do. We'll make judgments on winning the game, and if that means they'll play a little or a lot, that's what we'll do."
